delivering exceptional returns from installed capacity

BHP Billiton will today reaffirm its ongoing commitment to safely maximising returns on installed capacity at its Western Australia Iron Ore business (WAIO).

Speaking in Perth at the annual Global Iron Ore and Steel Forecast Conference, BHP Billiton President Iron Ore, Jimmy Wilson, will highlight the exceptional returns from the Company's productivity agenda.

"The effectiveness of our approach is validated by our robust financial and operating results despite the challenging market conditions," he said.

"For the first half of this financial year the team has delivered a solid underlying EBIT margin of 49 per cent and a return on assets of 34 per cent."

Mr Wilson will also reiterate WAIO is on track to achieve unit cash costs of less than US$20 per tonne(1) through a relentless pursuit of equipment availability and utilisation, efficient procurement and supply management and capital and workforce productivity.

He will also highlight BHP Billiton's strong and differentiated position in the Pilbara.

"Not only is our concentrated resource position a competitive advantage, but the quality and high-grade characteristics of our orebodies translates into premium products in the market," Mr Wilson said.

"The majority are high Fe Brockman and Marra Mamba ores, with low impurities and a high proportion of lump, around which we optimise our mine plans to maximise our profit margin.

"We can deliver high-quality product that our customers value, through existing hub infrastructure, at a low operating cost. Our footprint also means that we won't need to invest in new mining hubs to sustain current operations for decades."

BHP Billiton also anticipated the increasing supply of seaborne iron ore, approving the last of its major capital investments in its Pilbara infrastructure in 2011.

"Over the past decade, BHP Billiton made a US$25 billion capital investment in infrastructure and equipment in our WAIO operations. Through our disciplined program of investment, we were able to deliver valuable tonnes to market and maintain our share of supply," Mr Wilson said.

"We have no major projects in execution and our growth pathway will be achieved by continuing to make our existing infrastructure more productive.

"With this strategy we are maintaining Australia's competitive position in the global market and providing the revenue, royalties, employment and innovation that is so important for this country's future."

WAIO achieved record production of 124 million tonnes in the first half and is on track to deliver 245 million tonnes in the 2015 financial year (100 per cent basis).
